One-Volume Students' Guide to Torah Sheba'al Peh
Question: What to do when your teenager is spending too much time hanging out with friends and not enough time learning Torah? Answer: Sefer Hahinuch.
My mother has been teaching Sefer HaHinnuch in various settings for well over a decade, showing how it serves as a great one-volume introduction to Torah Sheba'al Peh. She has finally begun putting her teaching materials on-line, and when the next round of classes begins shortly, she will begin posting audios on-line as well. Highly recommended (pardon the nepotism)!
